For any chloride ion the charge is ALWAYS '-1'
So in AlCl3 can be split into its ions as 'A;l^(3+). and 3 Cl^(-)'
Note the charges MUST balance. the '3+' is balanced by three lots of (-).
First, the formula is AlCl3, with lowercase L's, not uppercase I's
The charge on the chloride ion (Cl-) is always 1-
Chloride ions have a charge of 1-. Since the charge on an Mg ion is 2+, the formula unit of Magnesium Chloride is MgCl2. There are 2 chloride ions for each Mg ion.
1-
negative
Barium ion, with a charge of +2.
Barium ion, with a charge of +2.
Each separate chlorine ion will have a charge of 1-. This is because chlorine has 7 valence electrons, so it needs one more electron to become stable.
The chloride ion carries a -1 charge.
Aluminum chloride
Chloride ion in AlCl3 has a charge of -1. The compound AlCl3 is aluminum chloride, which is an inorganic compound that can react with water.
Chloride ions have a charge of 1-. Since the charge on an Mg ion is 2+, the formula unit of Magnesium Chloride is MgCl2. There are 2 chloride ions for each Mg ion.
negative
1-
Barium ion, with a charge of +2.
The chloride ion has a negative charge of -1.
Barium ion, with a charge of +2.
The salt lithium chloride is LiCl. It's an Li+ ion and a Cl- ion.
CrCl3: A chloride ion has only a single negative charge; therefore, three of them are required to have the same magnitude of electric charge as a chromium (III) ion.
